Calibrated Direct-Read Variable RF Attenuators Deliver High Accuracy

To target medical applications, the model 794M calibrated 0-to-40- dB variable attenuator provides flat frequency response from 4 to 8 GHz. It also provides direct readout of attenuation values. The model 794M exhibits attenuation accuracy of 2.5 dB at the highest attenuation setting. It handles 10 W average and 5 kW peak RF input power. It exhibits insertion loss of 0.5 dB or less with a maximum VSWR of 1.25:1. The attenuator, which is housed in a rugged enclosure, measures 8.5 x 5.2 x 1.7 in. and weighs 5.7 lbs. It utilizes Type-N female input and Type-N male output connectors. The company also offers the model 794M for applications from 4 to 8 GHz with an attenuation range of 0 to 20 dB. It has identical characteristics to the model 794M except for accuracy of 1 dB at the highest attenuation setting.
